OTTAWA — The federal Liberal government plans to spend $4.5 billion to buy the Trans Mountain pipeline and all of Kinder Morgan Canada’s core assets.

Finance Minister Bill Morneau says that in return, Kinder Morgan will go ahead with its original plan to twin the pipeline this summer while the sale is finalized, which likely won’t happen until August.

Morneau says once the sale is complete, Canada will continue the construction on its own, with a view to eventually selling the whole thing down the road, once market conditions would allow it to get the best price.

Morneau presented the options during an early-morning cabinet meeting today before ministers made a decision on how to proceed.

Export Development Canada will finance the purchase, which includes the pipeline, pumping stations and rights of way along the route between Edmonton and Vancouver, as well as the marine terminal in Burnaby, B.C., where oil is loaded onto tankers for export.

Morneau says the federal government does not plan to be a long-term owner and is in negotiations with interested investors, including Indigenous communities, pension funds and the Alberta government.
